AbstractAbstract

[en] The photoluminescence study of the Er³⁺ ion in ErSc₂N ^rate^at C₈₀ and Er₂ScN ^rate^at C₈₀ fullerenes in the temperature range of 5 K to 80 K is presented. New emission peaks are observed for both fullerenes above 20 K. These peaks arise from thermally populated crystal-field levels of the excited state. An anomalous behaviour of the PL peak area is observed with an increasing temperature which reveals an internal rearrangement of the cluster ErSc₂N in ErSc₂N ^rate^at C₈₀.
